To all whom iii/may concern: Be it known that I, JOHN a citizen of the United- States, and a residentof Harrison, in the county bf Hamilton and State of Ohio, have invented cer-' tain new and useful Improvements in Sanitar Cow Stalls, of which the following is a; 1 111, clear, and exact description, referonce being had to the accompanying drawin formlng part of this specification.

31y invention relates to cow'stalls in which provision is madefor preserving them in a clean-condition.

It is a known factthat where a pointed object is arranged closely above the back of a cow, the animal will not be able to hump up whilein the stall until she backs up far enou h at the time of humping As a result stal s may be kept clean from droppii ige. 1 e above known fact has been utilized in several instances as a basis for devices to be-used in diary barns where cleanlinessof the animal, and particularly her udders, is a matter of vital importance;

The object of my invention is to improveupon, and render more practical devices for such purpose.

'"lows'have reielfeyce to a [re and stall conditions in various barns.

Among other objects I .desire to provide a member which 'is easily and quickly adjust able, 'andtjtorie which can be thrown out of the way readily, and dropped into position, whenleading the cow into her stall. My device is easily attachable to the stanchion over the cows stall and is adjustable both lengthwise and vertically of the stall, so as to take care of animals of. different sizes.

- I accomplish my objects bythat certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed. I 1

Figure 2 is a perspective of the device on a larger scale.

Fi re 3 is a pin ar.

Figure mountin arms in'their upper position.

The il ustration and'descrl tion that fol-i I i eri'ed embodi ment of my invention an are not intended as limitations of the invention to the exact details se torth. w

de'tail section through the 4. is a detail samba-er the Vermin Thecow-stall floor is shown at 1,-manuren trough at 2,,and cross stanchion at 3. In some stalls the cows head is placed between the uprights 4 between the floor and stanchion.

My device is provided with means for A clamping piece 7 is bolted to the portion 6, thereby completing a clamp about the stanchion for holding the arm in place. There will'usually be two arms, with rows of holes 8, extending along their length.

At the ends of the arms are mounted the half circle plates 9', which plates have a.

series of holes 10 extending throughout their length.

The pin bar isshown as formed ofa piece 0f wood 11, in which are pins l2 ar rangedun a row extending throughout its length and the bar is ,bolted by means of bolts 13 into the rocking frame- This frame is formed of one or more pieces and has the arms 14, 14, and the front ar' 15 to which the wooden bar 11 is bolted. The mounting or pivot bolts 16 for the arms 14 may be set in any one of the series of holes.17 in the arms, and of the series of holes 8 in the arms 5.

The holes in the two halfcircle plates are used for mounting the stop ins 18. There will be a pin arranged to llmit-the downward movement of the pin bar frame,

by forming a stop against which the arms 14 will' contact. .There will also be a pin 1 arranged tojprovide' a' stop for the upward movement of the frame arms 14.,

I provide the helical springs'19, which are secured to the mounting arms 5 and hooked into holes in the arms '14 of the pin bar frame.- The result of the springs and the pivoting of the frame arms 14 1s that a movement of the frame past. alignment with the arms 15 in .either direction will ire--- sult in the springs pulling the frame the rest of the way against the stop .pins.

/ 'In use'the operator will set the pivot bolts :i and the stop pins at such a point that the frame will he closely above the proper. POilt e she nohump up, wlthout,back ngv to a; position, where thestall W111 not be soiled,

' on the cows backto result in pronginfi cowwith the pins of the pin bar, shoul ter.

When taking the cow out of the stall the dairyman merely throws up the frame, past center, whereupon it will spring up well beyond any chance contact with the animal, 'andwhen the cow is back in her place, he will drop the frame, so as to bring the pins into position, ready to interfere with the cow soiling her stall, by inhibiting the act of humping up. P

In the case of a wooden stanchion, the arms 5 may be provided with plates 5 at their inner ends for screwing to the stanchions as illustrated in Figure 1. Round stanchions, will naturally require drilling a hole in the stanchion, so as to prevent the clamps 6, 7, (Figure 2) from slipping around, by setting a stop pin or set screw into the drilled holes and through the clamps.

The shape of the two half circle plates for the stop pins, permits of ready setting of-the. pins at any desired elevation for. the pin bar frames.

Having thus describedmy invention, what I claim as new anddesire to secure by Letters Patent, is 7 1. A device of the character described, comprising a pin bearing element for preventing humping of a cow, and means for mounting said element comprising a rocking frame on which the element is arranged, ad justable stops for limiting the movements of the frame to its upper and lower positions, and resilient means for holding the frame in its lower and upper stopped positions.

2. A device .of the character described, comprising a pin bearing element for preventing humping of a cow, and means for arms, and extending to both sides thereo stopped positions, when said rame is moved past center.

3. A device of the character described, comprising a pin bearing element for preventing humping of a cow, and means for mounting said element comprising a rocking frame on which the element is arranged, adjustable stops for limiting the movements of the frame to its upper and lower positions, and resilient means for holding the frame in its lower and upper stoppe positions, said adjustable stops comprising a perforated plate extending in an arc alongside of the frame, and ins located in the perforations in said p ate.

4. A device of the character described, comprisinga pin bearing element for preventlng humping of a cow, and means for mounting the element, comprising supporting arms, pivoting means on the arms, a frame for the pin bearing element pivoted to the arms by said means, stops for limiting the movements of the frame to its upper and lower positions, and spring means secured to the arms at one side of the ivoting means, and to the frame beyon said pivoting means, whereby the springs will act to pull the frame to its upper and lower stopped positions, when said frame is moved past center, said stops comprising a pair of are shaped plates secured to the supportin plates, and stop pins in JOHN WALTER KOLB.

and holes in the said holes.
